Carbon fiber composite drive shafts are not only lightweight, with excellent fatigue and corrosion resistance, but also produce low noise, have good vibration attenuation, and ensure high safety, making them particularly suitable for heavy-duty drive shafts in large machinery. Carbon fiber composite drive shafts can be categorized into two types based on their structural forms: integral and assembled. The integral type can be formed by continuous fiber weaving and curing, while the assembled type consists of two or more components connected and assembled into a single unit. The assembled type drive shaft is widely used due to its simple manufacturing process and good mechanical properties.

The drive shaft primarily withstands torque during operation. One of the advantages of carbon fiber composite materials is their high tensile strength. To bear large torques, the drive shaft must first ensure the continuity of the fibers. The hand-laid-up process, which uses carbon fiber fabrics for production, requires the fabrics to be cut into various diameters and shapes as per requirements. This results in individual fibers in each layer, lacking continuity, which significantly reduces the torsional performance of the carbon fiber tube.
